IMPROVEMENT IN MECHANCA. MOVEMENTS.

The Schedule referred to in these Letters Patent and making part: ofthe'same.

I, JAcoB W'OOLF, of Burr Oak, in the county of St. Joseph and State ofMichigan, have invented a new and .useful Improvement in MechanicalMovements, of which the following is a specification.

Nature and .Objects of the I nvcntion,

This apparatus acts on the same principle as that described in my patentof November 29, 1870.

My 'present improvements relate to- First, a device for maintaining theproper position of the levers, through Whose agency the power iscommunicated n Second, an improved construction of driving-shaft for usewith my mechanical movements.

Description of the Accompanying Drawing. Figure 1 is an end elevationvof my improved apparatus. Y

Figure 2 is a side elevation of the same.

General Description.

A A are a pair of standards, mounted on a bed, B, and supporting astationary shaft, C, which isformed with a bend, as shown at c, topermit the passage of the levers I.

C' represents a'partial continuation 'of the same shaft; andl A c', asecond bend, or crank, to be used with a duplex machine, as representedin my patent of -December l13, 1870.

The sleeve-shaft D, wheels E, (one ormore,) cranks G, eccentric annularweight H, (one or 1nore,) and lever I may be constructed and arranged asdescribed Claims.

What I claim as my invention is v 1. The bearing R S a', in combinationwith the 1evers I, wheel E, cranks Gr, and eccentric annular weight E,one or more, adapted to operate as described.

2. The stationary crank-shaft G, bent, as shown at c, in combinationwith the standards A A', levers I, cranks G, wheel E, and weight H,:ts-described.
